[FKVN-A112-999-A] Power Electronics Cooling Calculation at Room Level

posted Jun 22, 2017, 1:12 AM by Songyi Han

We will show flow calculations for the cooling of a complete 2.2 MW frequency converter enclosure. Here the pressure is generated by a radial fan and pushed through filters and grids. These components in the enclosure hardly generate any losses. The power electronics boards are equipped with heat sinks and it must be ensured that the air flow through the heat sink is sufficient. The flow behavior through inductive components like chokes and transformers is much more difficult to assess, as we have to ensure that all thin gaps between the windings are provided enough cooling air flow.
